How can you tell if your house has bad wiring? There are signs that can indicate this, and they are easy to spot.
Many homeowners don’t know that their wiring can be bad. Signs of poor wiring in your house are often small problems that you may overlook, but those small problems can lead to bigger issues down the road such as a fire.
Signs of bad wiring in your house
Faulty wiring is one of the five most common causes of fires. Outdated, damaged, or poorly installed and maintained wiring can be dangerous.
There are 15 warning signs that you should keep an eye out for:
1. Flickering lights or they go out
This is often the first sign of a bad wiring scenario. If you notice your light bulbs flickering, it could be due to one or more loose connections in your switch box and socket plugs that need tightening. There are many reasons that lights could be flickering and dimming. For instance, it could be a loose light bulb or an incompatible dimmer switch.
It’s also possible there might be a problem with wiring near a power source. The problem might also have to do with bad wiring like an overloaded circuit or faulty electrical components.
If lights go out completely, it’s very likely that the problem is in your switch box or socket plugs which need tightening. If this does not fix the issue it’s time to call an electrician to investigate further.
2. Appliances stop working unexpectedly could mean there’s a problem with the wiring
This is a very common sign of bad wiring. If there is an area of your home that seems to be having problems with electricity, find out if it is a switch, outlet, or anything that plugs in. If any wires are frayed, they should be replaced. You may also need to look for other signs of a rodent problem including in your air ducts.
According to the National Fire Protection Agency, 6400 electrical fire accidents were caused in the last 5 years due to damaged electrical wiring.
3. Electrical outlets spark when you plug in a device
Another common sign of bad wiring is if you notice sparks coming out from the electrical outlet when plugging in a device. This could also mean that there’s an issue with the grounding or the circuit breaker, so it’s important to investigate further and have your home inspected for any signs of damage.
4. Smoke that comes out of an outlet, light fixture, or other electrical devices is a serious problem that should be looked at immediately.
What you should do: When the smoke is coming from an outlet, quickly turn off the circuit and unplug the device, after that it’s time to call for help as soon as possible because this could be a sign that there are loose wires in your home and they’re close to overheating which poses a serious threat of electrical fire.

5. You see sparks coming from the wall socket or plugs, or you smell burning electrical wires.
What you should do: It is important to stay calm and quickly turn off the power at that outlet. It’s also smart to unplug any appliances that are plugged into the same circuit before calling an electrician.
6. Your home’s breaker trips frequently
If your breaker is tripping, it could be a sign that there’s something wrong with the wiring. This could happen if you have an older home. It can also mean that you’re using too much electricity in one place of your house (e.g. if too many appliances are on and the breaker trips).
If this is the case, it’s possible that your circuits are overloaded with too many appliances and fixtures. Have a professional come to inspect your whole electrical system.
7. Buzzing or crackling sounds in your home
A lot of people can hear electricity. You might be able to hear it too! But if you hear buzzing or crackling, that is not normal.
8. Aluminum or knob-and-tube wiring is old and should be upgraded.
These types of wiring are dangerous because they are old and don’t work well. You do not want to be sorry later.
9. Look out for warm, vibrating, or sparking outlets and switches.
An outlet might be hot. If there are any hot spots, something is wrong and you should hire an electrician.

10. Electrical Shocks
When you touch an appliance that has a proper grounding element, it will not shock you. If it does, then the grounding element might be faulty. Have someone come to check your electrical wiring so they can fix the problem before something bad happens.
Static electricity can make you feel a shock if you touch metal. If the air is dry, this could happen more. This is not a big problem and does not need to be worried about much.
11. Call an electrician immediately if smell burning or see scorch marks on electrical fixtures
Sometimes you can smell the wires burning/melting or they might leave black marks on the wall. This means that something is wrong with the electrical wiring and you should call an electrician as soon as possible.
Residential building electrical fires most usually started in bedrooms (15%) and attics or vacant crawl spaces (13%)
12. Loose Receptacle Connections
When you plug a cord into an outlet, it should be tight. Plugging the cord into a loose receptacle can cause problems.
The first problem is that any appliance plugged into that receptacle might not work.
The second problem is that if the plug partially falls out, there’s a risk of getting shocked when unplugging it.
The third problem with this connection is that friction from the loose connection produces more heat and might also lead to electrical fires.
13. Wiring In Your Home
Electricians do not need to make their wiring neat when they install it. There are no advantages or disadvantages to organized or messy wiring. But the organization of the wires can tell you something about the quality of work. If someone is very careful and clean, they’ll be more careful with their wiring job.
14. Rodent Damage on your wires
Rodents chew through wires in the walls of houses and this causes fires. 8% of house fires are caused by these creatures. They chew off the coating on wiring and they cause short circuits or heat that catch nearby materials, like insulation, on fire.
15. You have to reset your breaker box more than once a day
Circuit breakers sometimes trip. It’s usually because there is something wrong with the circuit. There might be a short circuit in an appliance or wire. The breaker may be tripping because it was overloaded, and this could happen if the breaker isn’t sized properly for the amount of electricity that is going through it.
